To it my. concern: 7 Beit known that LvHosmnn W. LEEDS, a citizen oftheUnited -,States, residing at-Seligma'n, in the county of. 'Yavapai and:State of Arizona, have invented certain new and useful Improvements in:Car Ventilators, of which the following is aspecification. 5

The, present invention'relates to that general type of ventilatorcovered by-my United States Letters Patent Nos. 948,144 and 1,211,602,and more especially to an improved ventilator adapted for use inpassenger cars. V I The principal objects of the invention are toprovide an eflicient ventilator which is compact in form; which iscleanly in 1ts operation; whichis adapted to be inserted readily in acar-windowor equivalent ventilatin opening without ;materiallyobstruct-v ing 51c vision, therefrom; and which may easily be removedand, if desired,-rev ersely inserted in a window-when the direction ofmovement of-the ear isjchanged; .-My im-- provedventilator isalsoadapted for use in 2 the deck Windowsof railwa cars, andis soconstructed. "and. arranged ft erem as to am tomatically and -thoroughlventilate the car when moving in either lrectlon.

Further objects and advantages of the illvention will appearas thenature thereof is understood from the accompanying description and'drawin whereina preferred embodiment is set orth for urposes ofillustrating the principle of t e lnvention and not as unnecessarilylimiting thescope of the appended claims.

In the drawing- Fig. lfis a top plan view of a railway car,

illustrating the Imanner in which the venti latorsmay be,adaptedlfor usein deck windows;

Fig; 3 is a horizontalj enlarged section.

through a ventilator mounted, in. a car window; and I Fig. 4 is avertical section taken on the hne 4-4'of Fig. 3." 4

With reference to the drawmg, the numeral 11 designates the jamb of awindow at the base of which is the sill 12. The sash 13 is partly raisedand permits the ventilator to be inserted in the-aperture between thebottom of sash 13, the sill 12 and the vertical sash guides 14.

The ventilator comprises a hood l6 slidably mountedupon a screenframe-17. The forward end and that side of the hood- 16 which is mountedon frame'17; are open.

a The upper and lower surfaces 18 of the'hood converge ,gshghtlytowards. their point of.

The rear closed junction with said frame. end 19- of the hoodmerges in agradual curve into the outer side wall 20.

A longitudinal partition 21 is vertically disposed 1n the hood parallelto side wall 20 for a major portion of its length. vSaid partiti'oncurves at its forward end toward and joins the inner side of hood 16,forming a funnel-like mouth as shown at 21 in Fig. 3.

The partition terminates at its. rearward end I at a point substantiallyopposite the begin- .ning of curvature of side jwall120 into'therear"wall 19'," thus formingimhood 16 a tortuous," air-entraining duct"leading from the -funnel-like opening 21? at the forward end of thehood, to that side of said hood spanned by the screen mesh off-frame 17An outstanding :flange 22- projeets vertically around the inner open,sideof the hood,

and is preferably formed continuous and integral therewith.

A keeper strip 23 is positioned on frame 17 and extends along both ofthe'horizontal frame members and one of the vertical mem- I bers.

strips about three sides of frame 17 receives the previously mentionedflange of the hood,

The groove thus formed by the keeper slidably inserted at that end ofthe frame having no keeper; In this way the hood is mounted securelyupon frame 17, and is pre-- vented from movement thereon by thewindow-and screen guides 14'when said frame 11s positioned in a window.Y

A plurahty of shutter leaves 24 arepivot ally mounted between thehorizontal members-ofiframel'lat such spaced intervals as to closeefiectively-"the screenedopening in said frame ,asmay be desired. Saidshut- A verticalpartition 27 is positioned near I the inner side of the.hood, and extends for ward from the'rear wall 19 to a pointsubstantiallyosite the rearward termination of 'partltlon 21. Partition27 is disposed parallel to the inner side to'the hood,iand only spacedtherefrom a-sufiicient distance to avoid interference with the operationof shutter leaves24r. The-purpose of said partition is to directforwardly the current of air entering through'the hood, and to di fiusethe same equally over the area of the screened frame.

Inasmuch as this type of ventilator 'is designed to be reversed in awindow when desired, that part of itwhich was the bottom naturallywouldbecome the top. Therefore the top and bottom portions of thehood, ill--cluding the construction therein, are duplicates of each other, and: thefollowing description of the bottom will suflice for the top. Aspreviously stated, the upper and. lower surfaces of the hood convergeinwardly, thus causing any rain water, cinders, or the like entering thehood to gravir tate toward the outer, lower side thereof.

A plurality of small apertures '28 are spaced inthe bottom of the hoodalong said outer side and serve to discharge any foreign matter such aswater, cinders, dust and the like carried by the air and entering thehood at its forward open end.. Another small aperture 29 may bepositioned in the bottom of the hood between the partition 27 and therear wall 19forthe purpose of dis-- charging therethrough any of theforeign matter which may have passed beyond apertures 28 and beyondabaffie plate 30 which extends across the bottom of the hood between therearward termination of the partition 21 and the side wall 20, as shown.At this point, in the lower portion of said side wall, is provided adischarge opening 31. Said bafie'plate 30 functionsto obstruct and todeflect any foreign matteninto the openin 31.

hen the direction of motion of a car equipped with. this type ofventilator is to be changed, the ventilators may be reversed in one oftwo] ways. 'Inthe first, the screened frame to which the hood isattached I may be turned end for end, in the window; alternatively thehood may he slid horizontally from its engagement with the keepers onthe frame,.reversed and again slid into the keeper ooves.

cleaning because the interior portion of the hood and inner side of thescreened frame carrying the shutters are quickly exposed by simplysliding said hood from its retaining keepers in the frame.

til ators, as illustrated in Fig. .1 maybe inmanages ate a suction whichdraws the air therefrom.

Thus with such an arrangement of the ventilating means, the carfis mosteiiicientlyventilated when traveling in either direction.

. ile the above detailed description is" basedupon an embodimentdesigned ticularly for use in passenger car win ows yet it will readilybe-seen that such a ventilator may advantageously be our loyed in manyother types of enclosed vehic es.
